Ensure Canvas

Stage of context setup during which you need to choose a canvas to paint on.

If you skip it and at the there is no canvas, then the addon work will continue but in a limited mode - obviously there will be nothing to paint on, but you can still work with import-export. If it is necessary to draw on an empty image and it is not previously in the file, the creation operator is provided. To quickly select an image, you can use the quick canvas selection operator.
